MEASURlNG-FAUCET.

SPECIFICATION forming part of Letters Patent No. 249,134, dated November1, 1881.

Application filed July 6, 1881.

To all whom it may concern Be it known that I, FREDERIC T. WILLIAMS, ofDe Wittville, in the county of Chautauqua and State of New York, haveinvented certain new and useful Improvements in Apparatus for Drawingand Measuring Liquids; and 1 do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it pertains to make and use it,reference being had to the accompanyingdrawings,which form part of thisspecification.

My invention relates to-an improvement in apparatus for drawing andmeasuring liquids and it consists ofa transparent graduatedmeastiring-chamber of peculiar form, attached by a suitabledelivery-pipe to the discharging end of a siphon, said pipe beingprovided with a suitable three-way cock for regulating the tilling andemptying of the chamber.

It further consists of a device for clamping the said chamber inposition and giving vent to both the said chamber and the barrel orreservoir to which the apparatus is attached,a device for registeringeach emptying of the measuring-chamber, and a device for exhausting theair from the siphon.

The object of my invention is to provide an apparatus which will by asimple movement draw, measure, register, and deliver liquids from abarrel or reservoir into any ordinary open or close mouthed vessel.

Figure l is a side elevation of the apparatus attached to a barrel, thesides of the exhaustcylinder and barrel being broken away. Fig. 2 is afront detail view, showing a portion of the registering device. Fig. 3is a partial plan view of the registering-wheel and operating mechanism.Fig. 4 is an enlarged sectional diagram of the clamping-screw andadjacent parts upon the vertical plane passing centrally through themachine from front to back. Fig. 5 is an enlarged section of thethree-way cock and adjacent parts upon the same plane as Fig. 4. p

The measuring-chamber A rests upon a hollow seat, B, and is clamped inposition by the hollow thumb-screw O, which thumb-screw (3 turns in theframe F and presses upon the cap (ModeL) J, holding both the cap J andchamber A in position. ,The chamber Ais apertured at the top and bottom,and rubber or other suitable packing is placed between the seat B andchamber A, and between the chamber A and cap J, to prevent leakage.

The frame F is right-angled at the point F, and fastened at the lowerend to the spout or termination 1) of the pipe E in front, and the upperend to the siphon-pipe G at the back.

On the top of the frame F, near the siphon G, is placed an uprightcylinder or pipe, H, extending upward to the level of the highest partof the siphon G,which pipe H is furnished with a piston, I, and isconnected with the pipe E by a small exhaust-tube, K, through anaperture in the frame F.

The filling and emptying of the chamber A is regulated by the use of thethree-way cock T at the junction of the hollow in the' seat B with thepipe E. The said three-way cock T is so constructed that when the handleQ is turned to the right to a certain point there will be an opencommunication between the siphonpipe G and measuring-chamberA throughthe pipe E, while the passage from the chamber A to the spout D remainsclosed. Turning the cock T to the left to a certain point cuts off theformer or supply passage and opens thelatter, allowing the liquid todischarge from the spout D. When turned midway between the two pointsmentioned the cock T cuts off both the supply and discharge. Alug orprojection upon the plug of the cock T, or an equivalent device, is madeto act as a double stop to prevent turning the cock T too far in eitherdirection.

The chamber A is given vent through the vent-tube M, which is joined tothe cap J, passes through the hollow thumb-screw G, and termnatesinsideof the barrel or reservoirL, through the bung or cover of the same. Thesiphon G passes also through the bung .or cover N and terminates at ornear the bottom of the vessel L.

At some point in the vent-tube M, preferably at O, is made an orificenormally closed by a pivoted pad, P, and spring S. The pad Pis connectedwith the cock T by a wire, R, and

elbow-lever V or equivalent device in such a manner as to raise the padP and open the orifice when the cock T is in position for dischargingliquid from the chamber A.

The chamber A is preferably constructed of glass, and its form is nearlythat of an inverted turnip, that form being advantageous for tworeasons: first, its near approach to the spherical form makes a chamberof given capacity require but asmall space as compared with ordinaryforms of graduated measures; sec ond, beingofsmall diameter near thetop,where small quantities are graduated, such quantities are moreaccurately measured than would be practicable with a cylindricalchamber. The chamber A is constructed to hold a definite quantity-as onegallon-and fractions of such quantity are marked in a scale, A, upon theside of the chamber A, the quantities indicated by said scale Aincreasing from the top downward. Graduating the scale A from the topdownward enables the operator to alwaysleave the chamber At'ull orfilling, and in readiness, when required, to draw oif any desiredquantity.

The apparatus may be attached to a barrel by a rod, Z, with right andleft screws turning in two blocks or heads,UW, and forcing them apartbetween the chines ot' the barrel. The siphon-pipe G, passing through anarm or projection upon each of the heads U YV, holds the apparatus inposition, as shown.

Having entered the apparatus into and attached the same to a barrel orreservoir containin g liquid, substantially as shown, the cock T isturned to the left to close the passage from the siphon G through thepipe E. The piston I is then somewhat forcibly drawn to the top of thepipe H, thereby exhausting the air from the siphon G through theexhausttube K. The siphon G will then fill with liquid from the vesselL. A stopper may be inserted in the top of the pipe H, to preventevaporation, or the piston I may be left in instead. The cock T is thenturned to the right, opening communication from the siphon G to chamberA, closing the outlet passage to spout D and slackening the wire R. Thepad P then closes the aperture 0 by the action of the spring S. Theliquid then flows from the vessel L through the siphon G and fills thechamber A, the air in the same passing at the same time through thevent-tube M into the vessel L. The chamber A having filled, theapparatus is ready for drawing 011 the liquid, and is designed to beleft in that condition when not in operation.

To draw off any desired quantity of liquid the cock T is turned to theleft, cutting off the supply to and permitting the liquid to dischargefrom the chamber A through the spout I), giving vent to the chamber A atthe same time through the tube M and orifice O, the pad P being raisedby the wire B. When the desired quantity has been discharged, if lessthan the full capacity of the chamber A, it will be shown by the heightof the surface of the liquid upon the graduated scale A when the cock Tshould be turned back to its former position, and the chamber A willfill as before.

If more liquid is desired to be drawn than the full capacity of thechamber A, the operation is repeated until the required quantity isobtained or the. contents of the vessel L exhausted.

Each discharge of the chamber A is registered by the wheel a revolvingin a horizontal plane upon the seat B as a pivot, having aseries offigures upon its periphery, each of which figures is brought to view insuccession at the opening I) in the frame F, the wheel a being movedforward one figure at each discharge by the sliding bar or frame 0,having a dog or wedge at either end, which work alternately in a seriesof slots through the rim of the wheel a, each dog or wedge turning thewheel onehalf the distance between the figures upon its periphery ateach forward and backward movement of the cock T, the bar 0 beingactuated by a spur or segmental gear, (1, upon the plug of the cock T,engaging the teeth of a rack, 0, upon the sliding bar 0.

The head W may be made solid with the frame F, extending back of thesiphon G, and, if preferred, the chamberA maybe constructed wholly oronly in part transparent, and equivalent devices may be substituted forseveral parts of the apparatus without departing from my invention.

Having thus described my invention, I claim- 1. The combination of thebarrel L with a drawing and measuring apparatus provided with the siphonG and vent-tube M, both of which pipes pass into the barrel through thebung-hole, and a clamping device which secures the apparatus to the endof the barrel, substantially as shown.
